SWIVEL ATTACHIVENT.

Application filed January 6, 1926. Serial No. 79,692.

rl'his invention relates to new and useful improvements in a swivel attachment.

@ne object oi the invention is te provide a swivel att chmentdesigned to be used in connection with the well known type ot ro tary swivel, used in well drilling by the rotary process, and by the use ot' which a single pair of elevators may be constantly carried by the traveling block 'tor connection to the swivel during the drilling process, as well as tor use in handling the drill pipe while the same is being made up in loweringl it into the bore, or is being'broken up in the process of withdrawal trom the bore.

ln rotary drilling it now the practice to equip the traveling block with a @hook which serves, at frequent intervals, to conf neet the traveling block to the bail ot the swivel being used while drilling; or the bail oit the elevator, used tor handling the drill pipe, at such times as it becomes necessary to suspend drilling operations to pull the drill pipe from, and return, it into the bore. ln breaking up and pulling this pipe, as conn nionly done the swivel and drill pipe connected thereto are elevated until the upper joint, or griet pipe can be disconnected. 'illus griet' pipe with swivelv attached is then swung to one side and lowered into the rat holetand the C{3f-hook is removed from the swivel bail and connected to the drilling` hook, and this hook is then connected to the elevator bail and the elevators are then applied to the drill pipe and the same is elevated and broken up into sections and removed from the bore. ln order to lower the pipe back into the bore to resume drilling the above described operations must be again performed in the reverse order.

By the use ot the swivel attachment herein described these operations may be much simpliiied by the use oi: an elevator which is constantly carried by the traveling block and a type of swivel attachment connected tothe swivel, and designed to receive the elevators, whereby the elevators may be connected to the swivel while drilling proceeds and applied to the drill pipe in withdrawing the same from, or lowering it into the bore.

lifi/'ith the above and other objects in view this invention has particular relation to certain novel features o'l construction, operation and arrangement of parts, an example ot which is given in this specification and illustrated in the accompanying drawings, wherein:

`Figure 1 shows a iront elevation oit a rotary swivel, with the attachment applied thereto and shown partly in section, and

Figure 2 shows a side elevation thereof.

Referring` now more particularly to the drawings, wherein like numerals of reterence designate similar parts in each of the figures the numeral 1 designates the upper joint of the drill pipe. This joint is commonly known as the griet' pipe, as it is operatively connected with the rotary drilling machine which drives the drill pipe beneath. The numeral 2 designates the swivel as a whole. This swivel has a swiveling connection with the griet pipe and is provided with a cose neck 3, providing for the connection ol' a hose to the swivel, through which water is pumped down through the drill pipe into the bore. The swivel has the op'positely disposed trunnions ll, 4.-, to receive the bearings 5. 5, into which the lower ends of the respective arms 6, G, are formed. The upper ends olf these arms are overturned and ot arcuate` formation thus presenting the confronting arcuate clamps 7, 7, whose ends have outwardly turned ears 8, 8, which abut and are bolted together to 'form an annular clamp collar which is secured around the tubular body 10, of the attachment. Above and below this clamp collar the body has the eX- ternal annular retaining flanges l1 and 12 respectively. The body is held in upright position, relative to the swivel by means of a surrounding element 1B, suoli as a cable which is secured to the arms 6, and surrounds the upper end of the swivel proper.

The body 10 is ext-ended above the retain Ying flange 11 thus providing a blank neck 14 to receive the ordina-ry type of elevators, as 15. The upper end of the neck 14 has an external annular flange 16 Jfor retaining the elevators in place and also has an eye 17, for convenience in handling the attachment and this eye has oppositely disposed ears 18, 18, adapted to engage in the elevator bails, or links, 19, 19, to prevent the swivel from turning and twisting or disrupting the rotary hose, above adverted to, in drillinof.

While drilling is in progress the swivel will be suspended, by the elevators, from the traveling block as shown. l/Vhen it is desired to withdraw the drill pipe the same may be elevated and broken up and then made up and again lowered into the bore, by the use of said elevators in the usual Way Without disconnecting the elevators from the traveling block. It is obvious that with a swivel adapted for a small size of pipe an elevator adapted for larger pipe may be used by inserting a. suitable bushing, as 20, within the elevator.

`What I claim is:

l. An attachment for swivels including side arms adapted to be pivotally connected to and to upstand 'from a swivel, a clamp collar carried b v the upper ends ot said arms, a tubular body fitted through said collar, retaining means retaining said body in said collar, said body being extended, forming an elevator receiving neck.

2. An attachment for swivels including` side arms adapted to be pivotally connected to and to upstand from a swivel, a clamp collar carried by the upper ends ot said arms, a tubular body fitted through said collar, retaining means retaining said body in said collar, said body being extended, forming an elevator receiving neck and an external ele 'ator retainer carried by the upper end oil said neck.

3. An attachment for swivels including side arms adapted to be pivotally connected to and to upstand from a swivel, a clamp collar carried by the upper end of said arms, a tubular body fitted through said collar, retaining means retaining said body in said collar, said body being extended, forming an elevator receiving neck and lateral ears carried by the upper end of said body adapted to engage the elevator bails.

4.-. An attachmentadapted for connection to a rotary swivel and having a neck adapted to receive a` pipe elevator, elevator retaining means on said neck above the swivel, and means for retaining said attachment in upright position relative to the swivel.

5. The combination of. a swivel attael|- ment having a plurality of flanges therearound adapted to be connected to a swivel and having a neck, of a pipe elevator adapted to be applied to said neck between two of said flanges and clamp arms also connected to said swivel and to said attachment.

C. The combination of a swivel attachment having a plurality ol' flanges therearonnd and adapted to be connected to a swivel and having a neck, of a pipe elevator adapted to be applied to said neck between two of said flanges and clamp arms also, connected to said swivel and to said attaclnnent and a lmshing interposed between lsaid elevator and neck.

7. An attachment for .swivels including means adapted to be pivotally connected to and to upstand from a swivel, a clamp collar carried bj; the upper end of said means, a body fitted through said collar, retaining means retaining said body in said collar, .said body being extended, forming an elevator receiving neck.

tu. An attachment for swivels including :ide arms adapted to be pivotally connected to and to upstand from a swivel, a clamp collar carried by the upper ends of said arms, a body fitted through said collar, retaining meaus retaining said body in said collar, said body being` extended, forming an elevator receiving neck and an external elevator retainer carried by the upper end of said neck.

In testimony whereof I have signed my name to this specification.
